The deliverymember or drum 4 is provided with an operating handle 7 extending through a slot 8. at one end of the cylindrical casing part 1, the end walls of said slot, 8, with said handle 7, serving as stops to limit the gscillatory movement of the delivery mem In accordance with the present invention the cylindrical casing .part 1, is provided with a lower extension part 9 having afdoor 10 secured by a lock 11, and constituting a coin box, the lower casing extension 9 being shown with a flat'rear wall 12 adapted to be secured to a suitable support (not shown). The delivery drum or member 4 is provided with trunnions 13, 14, engaging bearings 15,,

16, on the end walls 17, 18, on the cylindrical casing part 1, the end .wall 17 being formed as a separate plate and detachably secured in place, and said removable end plate 17 be ing provided with a central boss or projecting Hub part 19 at its inner side in which is formedthe bearing for the delivery drum trunnion 13. In the construction shown, the removable end plate 17 is provided with lugs 17, 17 and is secured by screws 2021 engaging said lugs and portions of the cas- 1 ing.

' able end plate 17 of the cylindrical casing part 1 is provided at its inner side with a segmental recess 22, an annular shoulder 23, and a peripheral flange, 24, and the central boss or hub part 19 has shoulder portions 25, 26. Fixedly secured-toithe removable end plate 17 at its inner side isa plate 27. The plate 27, which has a central opening, fits over the central boss or hub part 19 against 'the shoulder portion of the hub part 19 and the outer face of the peripheral flange 24 of the end plate, and is detachably secured to the end plate 17 by screws 28. Mounted for rotation on the central boss or hub part 19 of the removable end plate 17 between said plate and the plate 27 is a circular plate or disk.29. The circular plate or disk 29, which has an open central bearing to rotatably engage theboss or hub part 19, is held in place between the plate 27 and the shoulders -23 and 25 of the end plate, the engagement between the parts being such as to permit of free. independent rotation of the disk '29. The rotatable delivery member or drum 4 is coupled to the rotatable disk 29 against rotation relatively to the disk. The connection is made by a stud 30 on the end plate 4 of the delivery member or. drum detachablyengaging an aperture 31 in the disk 29, the stationary plate 27 being provided with a segmental slot 32 in which the e oted at one end to the part 38 on the plate 27 and has at its other end a locking tooth 38 that works through an .opening 39 in the plate 27. 40designates the spring for the detent or pawl 37 secured at one end to the plate 27 by a screw 41 and one of the screws 28, and at its other end engaging the outer end portion of the 'detent 37. The detent or pawl 37 has at one side intermediate its ends a pin 42 provided with aiconical shaped end, said pin extending through an openin 43 in the plat 27. The disk 29' normally, through its con ection with the delivery member or drum 4,-is yieldably held by the spring 6 in the ,.-position illustrated in -Fi ure 7 of thedrawings, the coin pocket of t e disk 29 being in alignment with a coin slot 44 in the peripheral flange 24 of theend plate 17 the plate 17 being shown asalso provided with an opening 45 to the side of the coin slot 44 to facilitate the insertion of the coin through said slot 44 into the coin pocket of the disk 29. With the disk 29 occupying the position referred to, the detent or pawl 37 occupies the position illustrated in Figure 11 of the drawings, the conical end of the pin 42 on .the detent extending into the groove 35 of the disk 29, and thelocking tooth 38" of the detent or pawl 37 projecting into the opening 36 in the disk 29 in position to engage the beveled'end wall 36. The opening 36 in. the disk 29 is of a length to provide for a limited rotary movement of the disk 29 before the beveled end wall 36 of the opening 36 in the disk will reach the locking tooth 38 of the detent 37. When a coin or check 46' of the proper size is inserted into the coin pocket of the disk 29 through the coin slot 44, upon rotation of the delivery drum or member 4 and disk 29 in 35 designates a.

the direction of the arrow .(see Figure 13) by .the operating handle 7, the coin or check 46 will engage the conical end of the pin 42 of the detent 37 and move the detent laterally so that its locking tooth1l38 will beiwithdrawn into the opening 39 ofthe stationary plate 27 out of the path of'the beveled end Wall 36 of the disk 29., and the disk 29 and the delivery member or drum 4 can be rotated to deliver atance, the parts being locked from, further movement by the locking tooth 38 of the detent 37 engaging the beveled end wall 36' of the opening 36 in the disk 29. The disk 29 may be and preferably is provided with" a plurality of teeth 47 adjacent the beveled end wall 36 of the opening 36 in the disk 29 to cooperate with the locking tooth 38 of the detent 37 to lock the disk 29 against rotation should the bevel end Wall 36 of the disk be broken or the locking tooth 38 of the detent or pawl be forced past thesanie in an attempt to operate the machine Without inserting the proper coin or check. I

Means is provided for positively ejecting the coin or check from the disk 29 in order to avoid choking or jamming of the mecha- V nism, and to guard against the operation of the machine more than once by the same coin or check in the coin pocket of the disk 29. The means for this purpose comprises an ejector member connectedwith the disk for movement therewith and to rock relatively thereto in combination with means for holding the ejector member from rocking movement during the first part of the rotary movement of the disk 29, and for rocking the same at the latter part of the rotary movement of the disk 29, the ejector member having a portion, which during its rocking movement travels radially outward in the coin pocket of the disk 29. Referring particularly. to Figures 7 to 10, and 14 and 15 of the drawings, 48 designates the ejector member in the form of an elongated flat plate part mounted in the recess 22 0f the end plate 17. The ejector member 48 is pivotally connected at one end to the disk 29 near its periphery by a stud 4.9 on one side of the ejector member engaging a bearing 50in the adjacent face of the disk 29, the side faces of the ejector member 48 slidably engaging the bottom wall of the recess 22 and the face of the disk 29.

' The ejector member near'its other end at one in the disk extending inwardly thereof from the bottom of the coin pocket of the disk.

At the other side located opposite the projection 51, the ejector member has a pin or laterally projecting portion 53, which slidably engages agroove or channel in the bottom wall of the recess 22. The groove .or channel, which extends from apoint in radial alignment with the central point of the coin pocket of the disk 29, for its greater part 54 is concentric with the axis of rotation of the disk 29 and terminates in a cam part 55. The ejector member 48 is provided at one side with a curved notched portion 56, and 57 is a pin or abutment part on the end plate 17 extending into the recess 22. In the inactive the ejector mem er 48 occupies the position osition of the mechanism,

29 is rotated in a feeding movement of the delivery drum or member 4, the ejector mem- '3' ber 48 will be carried around with the disk 29. During the greater part of the rotation of the disk 29, the ejector 48 through the'en- I gagement of the lateral projection 51. with the concentric part 54 of' the groove or channel in the end plate 17, .will he held from movement relatively to the disk 29, the ejector member 48remaining in the same position relative to the disk as that illustrated Figure 7. In the latter part of the rotary movement of the disk 29, as the lateral pr0- jection 53 of the ejector member travels through the cam portion 55 of the channel or groove (see Figure 8.) the ejector will be rocked relatively to the disk 29, and in this rocking movement its lateral projecting portion 51 will be caused to sweep radially outward from the slot 52 in the disk 29 into and through the coin pocket of the disk forcing the coin outwardly from the coin pocket through a slot 58 in the flange 24 of the end plate 17 into the coin box 9. In the rotation of the disk '29, the pin or abutment part 57 on the end plate 17 engages the curved notched portion 56 of the ejector member 48, as illustrated Figure 8, and assists in the rocking action. As will be understood upon the return movement of the disk 29 and delivery drum or member 4, the ejector member 48 Will be returned to the position illustrated Figure 7 of the drawings.

Means is provided to prevent the disk 29 and the deliverymember or drum 4 from returning to normal position after a coin or "check has been inserted in the coin pocket of the disk and the same partly turned, until the delivery member or drum 4 and the disk 29 have been moved through the full cup feeding movement and the coin or check has been ejected from the disk. Referring particularly to Figures 6 and 13 of the drawings, the means for this purpose comprises a series of locking notches 59 in the periphery of the end plate 4 of the delivery drum or member 4, and a pivoted spring held locking member 60 cooperating therewith. 'At either end of the series of locking notchesi59 is a larger opening or notch 61. The locking member 60 is pivotally mountedon a pin 62 on'the wall of the casing part 9 and works through an opening 63 in the cylindrical casing part 4. The locking member 60 is yieldably held in the position illustrated Figure 13 by a tension spring 64 connected with an arm 65 on the locking member 60 and a pin 66 on the casing part 9. The locking notches 59 are The construction illustrated Figures 1 to 15 of the drawings is adapted to operate with a penny, the coin-slot 44 and the coin pocket.

15 29 of the disk being of a size to just accommodate this size coin. constructed to operate with a minimum diameter of coin such as a penny and also with larger coins or checks up to a certain size.

Such a modified construction is illustrated Figures 16 and 17 of the drawings. In these views designates the removable end plate of the cylindrical part of the-casing, 71 thestationary plate member secured to the end plate 7Q, 7 2 the locking disk mounted for rotation between the end plate 7 0 and the plate 71, 73 the slot in the disk having the beveled end wall 73 74 is the pivoted detent or pawl and 75 the locking tooth of the pawl 3 adapted to cooperate with the beveled end wall 7 3 of the slot 7 3 in the disk 72. 76 designates the coin slot in the peripheral flange 77 of the end plate 72, and 78 the peripheral coin pocket of the disk 72. I

35 In this modified construction the coin slot 76 and the coin pocket 78 are constructed 4 e retained by the coin pocket 7 8 of the disk.

The diflerencebetween the two diameters of coins or checks, as will be understood, is provided for, as regards the operation of the detent or pawl 74, by the location of the lpck- I ing tooth 75 of the detent or pawl relatively to the beveled end wall 73 of the opening 7 3 in the disk 74, the distance between the locking tooth 75 of the detent or pawl 74 and the beveled end-wall 73 of the disk being increased, the mechanism readily lending itself to be operated through the coin or checks of different sizes within certain limits without requiring any material change in structure. It will be noted that by the particular construction and arrangement of parts hereinbefore set forth, a simple, practical form of coin or check controlled locking mechanism is provided which will be reliable and eflig dent in use. The special coin ejecting means functions in a positive way tofree the locking disk of the-coin or check, preventing choking of the mechanism and the operation of the machine more than once by a coin in the pocket ofthe locking disk. The construction is of a compact nature and, as

The machine may be will be appreciated the arrangement of the check controlled lockingmechanism' as a unit with the removable end plate of the casing, and the particular arrangement and detaclr able coupling of the mechanism with the goods delivery member or drum is of material advantage in the assembly of the parts.

While a specific embodiment of the inven-. tion is illustrated in the drawings, it will of course be understood that minor changes and modifications in the particular coin controlled mechanism shown, and the embodiment of the same in other forms associated with other forms of vending apparatus adapted forvending various kinds of goods, as will appeal to those skilled in the art and falling within the scope of the appended claims, may be practiced Withoutdep-arting from the spirit of the invention.
